SPECIFICATION forming part of Letters Patent No. 647,771, dated April17, 1900. Application filed February 3, 19Q0. Serial N0. 3,382. I(Nomodel.)

To all whom it may concern:

Be it known that I, LOUIS TOILLION,a citizen of the United States,residing at Hershey, in the county of Lincoln and State of Nebraska,have invented new and useful Improvements in Cultivators, of which thefollowing is a specication.

My invention relates to improvements in cultivators, and pertains to acultivator which is intended for a two or three row corn-listercultivator, all of which will be fully described hereinafter andparticularly pointed out in the claims.

- In the accompanying drawings, Figure 1 is a top plan view of acultivator embodying my invention. Fig. 2 is an enlarged detached viewof the disk attachment. Fig. 3 is an enlarged detached perspective viewof one of tivators are adapted to automatically follow` the furrows, andthat it also pertains to other details of construction wherein thecultivatnear their forward ends the transversely-extending beams C,lwhich carry at their outer projecting ends the parallel extending shortrunners D. Attached to the runners B, approximately at their centers andjust in rear of the runners D and the transverse beams C, is a platformE. This platform E is an attachable and detachable platform through themedium of the bolts a, which pass through the platform and into therunners. Extending across this platform E is a shaft F, which has itsends bent laterally and rearwardly, as shown at l?, the said shaftsbeingapproximately U shape in plan view. This shaft F is journaled insuitablel boxes c, carried by the said platform, and secured to theshaft F at a point intermediate its ends is a lever G, the said lever Gbeing provided with the usual ratchet-lever d, which is adapted to enthecentral and straight portion of theV shaft `and has its ends suitablyattached to the platform. -By means of this lever and notched sector theshaft can be oscillated as desired and locked in its adjusted position,for a purpose which will be explained hereinafter. The extremities ofthe laterally-turned portions of the shafts are provided withhorizontally-arranged enlarged portions c,which are preferably circularin form and provided with projections. This enlarged portion e has acentral bolt-opening f and a short spindle or shaft g, which has itsinner end enlarged, as shown at t', and also provided with projectionsto engage the projections upon the shaft enlargement e, and the enlargedportion z' of the short spindle or shaft is provided With acentrally-arranged bolt-opening j, adapted to register with thebolt-opening in the enlarged portion e of the said shaft and throughwhich a clamping-bolt k passes for the purpose of clamping and lockingthe short shaft or spindle to the end of the shaft F at the desiredangle for the purpose of cultivating as required. Journaled upon theshort shafts or spindles gare the cultivator-disks m, which are providedwith hubs u, adapted to freely rotate upon the said spindles. From thisdescription' it will befseen that the cultivater-disks through themedium of their adjustable shafts or spindles are adapted to be adjustedat any desired angle in relation to the shaft F or the runners of thesled portions of the cultivatorsA and that the vdisks are readily andquickly thrown into or out of operation by oscillating the shaft Fthrough the medium of the operating.- lever G. Through the medium ofthis operating-lever the disks can also be made to cut the desired depthin the soil, according to the adjustment of the shaft, as will bereadily understood.

While a cultivator comprising a sled and the disk attachment justdescribed is adapted to be used singly, yet I prefer to use thesecultiva-tors in plurality and preferably three in number side by side,as illustrated in Fig. l. When used in series, as there shown, it isdesirable and, indeed, necessary to provide IOO cultivators toautomatically follow the fur- IIS rows in which they are placed. This Iaccomplish by the draft-evener, which I will now describe. e Y

The evener consists of an ordinary doubletree I, which is directlyconnected withv the central'cultivator through themedium of theflexible-chain connection J. Situated just in rear of this doubletree' Iare the two elongated draft-bars K, which have their inner endsconnected, by means of suitable links L,

with the doubletree at opposite sides kof its center, and thesedraft-bars K have connected with'their outer ends the singletrees Thetwofoutside cultivators are connected with the draft-bars K at pointsnear their outer ends by means of the flexible-chain draft connection N.By means of this ,con-

struction the cultivato'rswillv automatically follow the furrows of therows, the links L permitting the draft-bars K to lseparate and approachor yto'relatively expand or contract in opposite directions, whereby theunevenl movement. ofthe horseswillnottendto-cause the cultivators to bedisplaced fromthe furrows. N

By 'the above arrangement a boy and four `horses can do the-work ofthree lmen andsix horses when cultivating corn inV the usual way. Y v

vIt will bes-noticed that the-central-'cultiva- -tor vis provided-with aseat P just back of the platform forthe driver. y Inoperation the short`runners D-ridev on the'ridges or edges of the furrows and constituteguides to make the sled run level and serve alsoto-keep the sled fromrocking sidewise. v`Iheselrunners also serve to cause the disks to jcutanr even depth on either vside,

and therefore serve very important functions. Having thus described myinvention, what I claim, andldesire to secure by Letters Pat- ",ent,is yAl. :A cultivator comprising a supporting' frame,atransversely-'jo'urnaled and vertically-oscillating v approximately U-shaped shaft, a lockffor said shaft adapted .to lock' it firmly atVarious points of its oscillation, short spindles carryingcultivator-disks horizontally `adj ustably connected with the ends ofsaid shafts, anda lock for said short spindles for locking thcmatvarious points in their horizontal adj ustment,su'bstantially as d escribed.

2. A'cultivatlor comprising a sled, atransversely-arranged shaft carriedby a supporting-frame, the ends of the shaft turned yrear, wardly,short'disk-carrying spindles horizontally ladj ustablyconnected with theextremities of the rearwardly-turned ends of the shaft, and-a leverconnected with thesaid shaft at `a point intermediate its end forlthepurpose ,of oscillating the shaft and thus `throwing thecul-tivator-disks in or out of op` eration for causing them to out inthe soil' 4. A cultivator comprising a supportingframe, a shafthavinga'straight portion transversely journaled upon thesupporting-frame, the ends of the shaft turned rearward, shortcultivator-diskcarrying shafts horizontally adjustably connected withthe rearwardlyturned ends of vthe said shafts,'an operatingleverconnectedwith the straight central portion of the shaft, anotched sectorextending over the shaft with its ends -connected with thesupporting-frame, andthe lever having a locking member adapted `toengage the v notched. sector, substantially as described.

;-A-cultivator comprising a supportingframe, an oscillating-shaftsupported by the said frame and having laterally-turnedends, the ends oftheshafts having horizontallyenlarged portions, Vshort disk-carryingshafts with corresponding enlarged horizontal yportions, theenlarged-portions having `registeringbolt-openings, bolts passingthrough the said openings, `and the engaging faces of the enlargedportions of the shafts having a clutch-like` structure whereby thedisk-carryinggshafts maybe osoillated,fandthe diskshafts-adjusted,substantially as described.

6. .A cultivatorcomprisin g parallel runners,

.1a-detachable'.disk-carrying platform' having a v transverselyjournaled oscillating shaft, means for oscillating'the shaft, theends ofthefshaft turned rearwardly and short diskcarrying shafts horizontallyvadj u stably ,connected with the rearwardly-turned ends of theVoscillatingshaft, substantially .as described. r i

7. VA cultivator comprising parallel elongated runners B,transversely-extending bars C having their ends extending to oppositesides of the said parallel runners, lshort parallel 'runners D connectedto the outerends lofthe bars C, anda transversely-extendingdisk-carrying shaft supported bythe elongated runners at a' -pointinrear ofthe short runners, substantially kas described.

l Intestimony'whereof Ihave hereunto set my hand inthe presence of twosubscribing witnesses.
